I finally got this to work using Ubuntu. My firewire says disabled in the service menu, but no problems capturing from Paladia content that was DVR'd.
Here is my solution from the AVS thread:

After reading through this entire thread, I have found the best to capture video from my 8300HD after much trial and error.
I used a Dell E5410 with Windows 7 Enterprise 32bit with the following results:
I tried VLC. It worked, but choppy video and sound.
I tried TSReader Lite. Same issues with choppy video and sound
I got a demo of Adobe Premier Elements. I couldn't even get it to capture without crashing.
I then thought about Linux since I have Ubuntu 11.04 dual booting on this machine. I am no means an linux expert, but was able to capture flawless 1080i video with test-mpeg2.
Ubuntu 11.04 should come with the necessary components to make this work. Being a linux novice, it took me several days to realize my problems when trying to use test-mpeg2.
You should have a folder named libiec61883-1.2.0. If you don't download it's tar from the web and extract it wherever.
Once extracted open terminal and go to the extracted libiec61883-1.2.0 folder. Then do a ./configure and make. Then go to examples folder in libiec61883-1.2.0. This is where test-mpeg2 resides.
Connect your 8300hd and type plugreport in the terminal window under libiec61883-1.0.0/example.
You should see the firewire nodes. My device was under node 1.
I then issued the following command ./test-mpeg2 -r 1 > test.m2ts .
Then I saw starting to receive below. To stop capturing hit ctrl+c .
At that point I viewed the file with VLC in linux. I got concerned because it was choppy with image tearing. I then copied that test.m2ts to my windows C:\ drive . Then booted into Windows 7 and it played 100% flawlessly.
test-mpeg2 is rather crude with its command line operation, but it is the best method I have found for the 8300HD.
